In a moment that blended diplomacy with a dash of tech humor, Chinese President Xi Jinping presented South Korean President Lee Jae Myung with a pair of Xiaomi smartphones during a state visit in Gyeongju, South Korea. The exchange, which occurred on Saturday following the Asia-Pacific Economic Cooperation forum, saw Xi jokingly advising Lee to “check if there’s a backdoor,” a quip that elicited laughter but underscored deeper tensions in global technology and security.

The gift was not just a casual gesture; it highlighted China’s push to promote its homegrown tech brands amid escalating U.S.-China rivalry. Xiaomi, a Beijing-based company known for its affordable yet advanced devices, has been expanding globally, challenging giants like Samsung in markets including South Korea. According to reporting from Reuters, the smartphones’ displays were manufactured in South Korea, adding a layer of irony to the presentation in the homeland of Samsung Electronics.

A Diplomatic Gift with Tech Ambitions

Xi’s visit marked his first to South Korea in 11 years, a period marked by strained relations over issues like North Korea and U.S. alliances. The Xiaomi phones symbolized China’s technological ambitions, as outlined in its recent five-year economic plan, which emphasizes self-reliance in semiconductors and consumer electronics. Lee reciprocated with a high-quality wooden Go board, a nod to cultural ties, but the spotlight remained on the phones.

Industry analysts see this as part of Beijing’s strategy to normalize Chinese tech in allied nations. “It’s a subtle promotion of Huawei-like alternatives without the baggage,” noted one Seoul-based tech consultant, referring to past U.S. bans on Huawei over espionage fears. The backdoor joke, while lighthearted, evoked real concerns about hidden vulnerabilities in devices, a topic that has plagued international supply chains.

Security Jokes Amid Real Espionage Fears

The term “backdoor” refers to unauthorized access points in software or hardware, often linked to state-sponsored spying. In the context of U.S. accusations against Chinese firms, Xi’s remark could be interpreted as a playful deflection. As detailed in a piece from The New York Times, Lee inquired about the phones’ security, prompting Xi’s laughing response: “You can check if there’s a backdoor.”

This isn’t the first time tech gifts have stirred controversy. Similar incidents, like Venezuelan President Maduro praising a Huawei phone for being “unhackable by gringos,” highlight how devices become proxies in geopolitical games. For Xiaomi, which has faced scrutiny in India and elsewhere over data privacy, the endorsement from Xi could boost its image, though it risks amplifying suspicions in Western-aligned countries.

Implications for Global Tech Rivalry

Beyond the humor, the episode reflects broader shifts in Asia’s tech ecosystem. South Korea, a key U.S. ally and semiconductor powerhouse, is navigating pressures to decouple from Chinese supply chains. Yet, economic interdependence remains strong; Chinese firms like Xiaomi source components from Korean suppliers, creating mutual benefits.

Experts warn that such diplomatic overtures could influence trade policies. “If South Korea warms to Chinese tech, it might complicate U.S. efforts to isolate Beijing,” said a policy analyst at a Washington think tank. Coverage from The Jerusalem Post noted the nervous laughter at the event, suggesting underlying unease about potential cyber risks.

Future of Sino-Korean Tech Ties

As both nations eye advancements in AI and 5G, this gift exchange may signal thawing relations. Xiaomi’s market share in South Korea is growing, driven by competitive pricing and features. However, security audits of Chinese devices are likely to intensify, with governments demanding transparency.

In the end, Xi’s joke encapsulates the delicate balance between innovation and suspicion in international tech. While it lightened the mood, it also reminded industry insiders of the persistent shadows of cyber threats in an interconnected world. As one observer put it, in diplomacy as in technology, what’s hidden often matters most.
